NAME

       MPI_Attr_put  -  Stores  attribute  value  associated with a key -- use of this routine is
       deprecated.

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Attr_put(MPI_Comm comm, int keyval, void *attribute_val)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_ATTR_PUT(COMM, KEYVAL, ATTRIBUTE_VAL, IERROR)
            INTEGER   COMM, KEYVAL, ATTRIBUTE_VAL, IERROR

INPUT PARAMETERS

       comm      Communicator to which attribute will be attached (handle).

       keyval    Key value, as returned by MPI_KEYVAL_CREATE (integer).

       attribute_val
                 Attribute value.

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       Note that use of this routine is deprecated as  of  MPI-2.  Please  use  MPI_Comm_set_attr
       instead.

       This deprecated routine is not available in C++.

       MPI_Attr_put  stores the stipulated attribute value attribute_val for subsequent retrieval
       by  MPI_Attr_get.  If  the  value  is  already  present,  then  the  outcome  is   as   if
       MPI_Attr_delete  was  first called to delete the previous value (and the callback function
       delete_fn was executed), and a new value was next stored. The call is erroneous  if  there
       is  no  key with value keyval; in particular MPI_KEYVAL_INVALID is an erroneous key value.
       The call  will  fail  if  the  delete_fn  function  returned  an  error  code  other  than
       MPI_SUCCESS.

NOTES

       Values  of  the permanent attributes MPI_TAG_UB, MPI_HOST, MPI_IO, and MPI_WTIME_IS_GLOBAL
       may not be changed.

       The type of the attribute value depends on whether C or Fortran is being used.  In  C,  an
       attribute  value is a pointer (void *); in Fortran, it is a single integer (not a pointer,
       since Fortran has no pointers and there are systems for which a pointer does not fit in an
       integer, e.g., any  32-bit address system that uses 64 bits for Fortran DOUBLE PRECISION).

       If  an attribute is already present, the delete function (specified when the corresponding
       keyval was created) will be called.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and
       Fortran  routines in the last argument. C++ functions do not return errors. If the default
       error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then  on  error  the  C++  exception
       mechanism will be used to throw an MPI:Exception object.

       Before  the  error value is returned, the current MPI error handler is called. By default,
       this error handler aborts the MPI job, except for I/O function errors. The  error  handler
       may    be   changed   with   MPI_Comm_set_errhandler;   the   predefined   error   handler
       MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not
       guarantee that an MPI program can continue past an error.
